You did not win the $640 Mega Millions jackpot this past Friday. But neither did all of the idiots out there who tried to fake it—some of them pretty darn convincingly. Dr. Neal Krawetz over at the Hacker Factor blog went out and squashed one of the especially convincing fakes. Here's how.

The fake was originally posted on Reddit before a lot of details had come out about the winners, so some obvious things like it being from a state that didn't have a winner weren't readily apparent. But even beyond the obvious, there were a few technical methods that Krawetz used to debunk the trickery. All of it is documented in detail and with screenshots for the less Adobe-adept among us.
